Oracle Cloud Infrastructure for Solutions Architects

By: Prasenjit Sarkar

Overview of this book

Oracle Cloud Infrastructure (OCI) is a set of complementary cloud services that enables you to build and run a wide range of applications and services in a highly available hosted environment. This book is a fast-paced practical guide that will help you develop the capabilities to leverage OCI services and effectively manage your cloud infrastructure. Oracle Cloud Infrastructure for Solutions Architects begins by helping you get to grips with the fundamentals of Oracle Cloud Infrastructure, and moves on to cover the building blocks of the layers of Infrastructure as a Service (IaaS), such as Identity and Access Management (IAM), compute, storage, network, and database. As you advance, you’ll delve into the development aspects of OCI, where you’ll learn to build cloud-native applications and perform operations on OCI resources as well as use the CLI, API, and SDK. Finally, you’ll explore the capabilities of building an Oracle hybrid cloud infrastructure. By the end of this book, you’ll have learned how to leverage the OCI and gained a solid understanding of the persona of an architect as well as a developer’s perspective.

What this book covers

Chapter 1, Introduction to Oracle Cloud Infrastructure, introduces OCI and the fundamentals of OCI as second-generation cloud computing to prepare you for a technical deep dive in the forthcoming chapters.

Chapter 2, Understanding Identity and Access Management, includes a technical walkthrough of governing and managing OCI's IAM principles. It will explain how to manage access to your cloud resources.

Chapter 3, Designing a Network on Oracle Cloud Infrastructure, educates you about the setup process of virtual cloud network (VCN) resources. You will learn about the VCN components and typical scenarios of VCN deployment. This chapter describes various methods of connecting to your OCI instances and configuring network access between on-premises infrastructure and the OCI data center.

Chapter 4, Compute Choices on Oracle Cloud Infrastructure, covers different options of computing nodes. This chapter describes various choices of compute within OCI and how to operate them as per your application's requirements.

Chapter 5, Understanding Oracle Cloud Infrastructure Storage Options, introduces the vast storage options to choose from for your various different storage needs. You will learn how to pick and choose which storage option is best for your application.

Chapter 6, Understanding Database Choices on Oracle Cloud Infrastructure, discusses OCI database operations and how to manage Autonomous Database.

Chapter 7, Building a Cloud-Native Application on Oracle Cloud Infrastructure, discusses modern application development on OCI using OCIR, Cloud Shell, and OKE. You will learn how to create an OCIR repository to store your application container images, how to create a Kubernetes cluster and operate it, how to use Cloud Shell for zero local dependency setup, among other things.

Chapter 8, Running a Serverless Application on Oracle Cloud Infrastructure, demonstrates the use of Oracle Functions as standalone serverless computing as well as integration with OCI Events as event-driven code execution.

Chapter 9, Managing Infrastructure as Code on Oracle Cloud Infrastructure, discusses how to use Object-Relational Mapping (ORM) to create infrastructure blocks using Terraform code. You will also see how to integrate ORM with GitLab for version control of those Terraform scripts. You will also run a CI/CD pipeline and learn how ORM can help generate Terraform code from existing OCI resources in an account.

Chapter 10, Interacting with Oracle Cloud Infrastructure Using CLI/API/SDK, discusses how OCI introduced a rich set of tools around REST APIs, such as SDKs and the CLI. You will learn how to use these tools to interact with OCI and perform operations on OCI resources.

Chapter 11, Building a Hybrid Cloud on Oracle Cloud Infrastructure using Oracle Cloud VMware Solution, discusses the modern hybrid cloud solution using VMware on OCI. You will learn how to deploy an Oracle Cloud VMware Solution (OCVS) solution and its connectivity.
